Amazon Selling Partner API 'Too Many Active Keys"

Question

I'm able to generate a new access token using a refresh token that I have, however when I go to use that access token in a request to SP-API I get a 429 error:

{
    "errors": [
        {
            "message": "Too Many Active Keys",
            "code": "InvalidInput"
        }
    ]
}

I can't find in any documentation exactly what this error means? I haven't made any requests to SP-API in the last 24 hours so I don't believe that I have been rate-limited.
